NL1-B100 1P Surge Protection Device
Spark Gap Surge Arrester
(B+C Combined Arrester )
NL1-B series surge protective device(in short: SPD, alias:surge protector, surge arrester)is suitable for TN-S. TN-C-S. TT. IT etc.power supply system of AC 50/60Hz.≤380V,and used at the equipotential connection,which protects the electric network not shocked by the thunder and lightning, it’s designed according to GB18802.1. IEC61643-1,it adopts 35mm standard rail,there is a failure release mounted on the module of surge protective device.When the SPD fails in breakdown for over-heat and over-current,the failure release will help electric device separate from the power system and green meas normal,red means abnormal,Kevin wiring mode,remote-signaling output interface.it’s also could be replaced for the module when has operating voltage.
NL1-150. NL1-120. NL1-100 series surge Protective devices are suitable for B grade surge potection, used at the equipotential connection of LPZOA or LPZOB and LPZ1 zone,which protects the electrle network not shocked by the thunder.NL1-80. NL12-60series surge protec tive devices are usually installed in low voltage main distri bution box connected to the incoming end of the buildings.
Notice:When you order our goods,please write the model and quantity carefully.For example:NL1-B150/4-385,8 pieces.
